SQL - Nested result instead of merge when left join - mysql

Question

I have a SQL LEFT JOIN like this:
var getEmail = req.body.email;
const connection = require('../conig/db');
let promise = await new Promise((resolve,reject)=>{
connection.query("SELECT users.id, users.account_id, users.email, accounts.id, accounts.company FROM users LEFT JOIN accounts ON accounts.id=users.account_id WHERE users.email = ?",[getEmail], function(err, rows) {
if (err) {
console.log(err);
resolve();
}
console.log('rows:');
console.log(rows);
resolve();
});
});
The result merges the columns:
[{
id: 1,
account_id: '1',
email: 'user01#domain',
company: 'Company 01'
}, {
id: 3,
account_id: '3',
email: 'user02#domain',
company: 'Company 02'
}, {
id: null,
account_id: '',
email: 'user03#domain',
company: null
}]
But what I would like to have is a nested result with the table name at first level like this:
[{
users: {
account_id: '1',
email: "user01#domain",
id: 1
},
accounts: {
company: "Company 01",
id: 1
}
}, {
users: {
account_id: '3',
email: "user02#domain",
id: 2
},
accounts: {
company: "Company 03",
id: 3
}
}, {
users: {
account_id: '',
email: "user03#domain",
id: 3
},
accounts: {
company: null,
id: null
}
}]
How can I achieve this?
I tried:
SELECT users.id AS users.id, users.account_id AS users.account_id, users.email AS users.email, accounts.id AS accounts.id, accounts.company AS accounts.company FROM users LEFT JOIN accounts ON accounts.id=users.account_id
-> Error
